LAB GRUPPEN D 20:4L_US1 2000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications (D 20:4L_US1)

LAB GRUPPEN D 20:4L_US1 2000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications (D 20:4L_US1)

The D 20:4L harmonizes 2000 watts of adaptable power with cutting-edge LAKE DSP, DANTE digital audio networking, and advanced system integrity monitoring.

The D 20:4L inherits its robust, high-power amplifier technologies from our acclaimed PLM Series—an amplifier platform celebrated for its reliability and audio performance in demanding scenarios, including global concert tours and high-profile installations. Tailored for digitally networked sound applications in large commercial settings like stadiums, arenas, and performance venues, the D 20:4L integrates LAB GRUPPEN's renowned reliability and sound quality with updated output stage technologies. These advancements, coupled with installation-specific hardware and software features, streamline amplifier system design, curbing initial equipment expenses, and minimizing long-term energy consumption for end users.

Rational Power Management (RPM)

The D Series is anchored by Rational Power Management (RPM), LAB GRUPPEN's exclusive technology empowering system designers and integrators with unparalleled freedom in distributing output power across each channel for optimal performance under specific load conditions. RPM not only enables cost reduction but also mitigates the need to over-specify amplifiers typically seen in conventional installations. This alleviates the common issue of excessive power on some channels while others remain underutilized. For instance, the D 120:4T/Ta can harness up to 5000 W of power output on two channels, allowing for smarter allocation of available power to accommodate less demanding loads across the remaining channels.

CAFE for Green Credentials

The D 20:4L offers configurability and monitoring through the innovative CAFE (Configuring Amplifiers For the Environment) software suite. This powerful tool not only facilitates comprehensive system surveillance and RPM configuration but also features the Equipment Specification Predictor (ESP). ESP analyzes system requirements, suggesting optimal specifications for the D Series units including model and quantity needed, heat generation, channel distribution, and current draw. This thorough analysis results in precise mains management and accurate specific.

The Power of LAKE Processing

The D Series LAKE amplifiers offer unparalleled input flexibility, leveraging exclusive LAKE processing algorithms for powerful performance. These models boast comprehensive control and load monitoring via the LAKE Controller and seamless integration into Dante digital audio networks. Additionally, through third-party middleware, they can integrate into other widely used networked digital matrix systems. Each D Series LAKE model incorporates four full-featured LAKE Processing modules, delivering four discrete channels of audio throughput input to output. This includes selectable audio signals from analog and digital channels, ensuring adaptability to various setups. The onboard LAKE processor provides advanced group control with Raised Cosine™ MESA EQ™ asymmetric filters, catering to diverse loudspeaker systems. Furthermore, the LimiterMax™ peak and RMS limiters set a benchmark for loudspeaker protection and sonic transparency.
